500X I/P Transducer

Type EAA-500 I/P,E/P transducer(I/P,E/P converter) converts a current or voltage input signal to a linearly proportional pneumatic output pressure. This versatile instrument is designed for control applications that require a high degree of reliability and repeatability at an economical cost.

Calibration of electropneumatic transducer

As a standard instrument, the electropneumatic transducer needs to be individually calibrated for accuracy, but in actual use, it is generally combined with the connected regulating valve to achieve joint calibration in order to reduce the workload.

Ready to work

The required instruments for calibration: a standard current signal generator, a standard pneumatic barostat, a 0.1 precision standard pressure gauge, and a standard millimeter ruler.

Calibration connection: the standard current signal generator is connected to the T1500 transducer junction box; one end of the standard pneumatic barostat is connected to the instrument wind and the other end is connected to the instrument wind inlet of the electropneumatic transducer, and the output of the barostat is adjusted to a constant 140KPa ,; Connect the standard pressure gauge to the air path between the electric converter and the pneumatic control valve through the instrument air pipe, measure the stroke indicator of the control valve with a millimeter ruler, and mark the initial position.
